Hi @gottires, and welcome!

I’m sorry to see you’re having some difficulties… I unfortunately can’t seem to see the screenshot you shared (it doesn’t load), so I believe we would need additional details (and/or another attempt at sharing a screenshot). For instance:

Do you have one or multiple NIC? If multiple, does this error happen for all of them?
Was anything changed recently on the machine, hardware-wise?
What kind of NIC is it (ethernet, infiniband, …)?

Also, what version of Rockstor are you using? Did you activate one of the update channels (Testing or Stable) and applied all updates? Ideally, the output of yum info rockstor would give us all the needed information.

I’m sorry for having more questions than answers, but I feel we have to get more information to see what happened here.

Hope this helps,
